Induced voltage and torque calculation.<br />
• The induced voltage after rectification is:<br />
E a = K Φ f ω m = K K f I f ω m = K m I f ω m<br />
• The out put power if the losses are neglected is:<br />
P dc = I a E a = T m ω m .<br />
• The torque is:<br />
T m = I a E a / ω m = K Φ f I a = K m<br />
